The clever trick here, though, is that the wall is placed next to a blue water feature. Blue is directly across from orange on the color wheel, and the contrast between the two strengthens the colors of both.
So perhaps that is why the designer chose it to be the dominant color in this otherwise subdued gray seating area. The orange doesn’t overpower the planting; as with the water feature in a previous image, the blue-gray of the concrete empowers the warmth of the orange.
Cleverly the designer has linked the orange throughout the design — from the leaves of the Crocosmia to the flowers of the Canna and even the parasol. The eye is led smoothly through the garden by a color that’s thought of as being brash and garish, but that here is warm and calming.
Tell us: Will you be letting orange out of your living room and into the garden?
